Full Text: 1988\Tra Met Che13, 39.pdf Abstract: The kinetics of reduction of molybdenum(VI) and tungsten(VI) ions by NaBH4 in buffered aqueous solution have been investigated. The reaction rate depends upon the first powers of the concentrations of the reactants. The temperature was varied, and the activation parameters were evaluated. Chemical and spectral evidence for the formation of molybdenum(V) and tungsten(V), as the reaction products, is presented. Plausible mechanistic pathways for these reactions are suggested.

Full Text: T\Tra Met Che25, 599.pdf Abstract: The kinetics of the oxidative color removal from congo red dye using H2O2 in conjunction with transition metal ions supported on ZrO2 were studied. The rate of reaction is first order on H2O2, the catalyst, and in congo red. It attains a limiting rate at higher concentrations of reagent. Also, the rate of reaction decreases with increasing [H+], due to protonation of the substrate amino groups, as well as to the low deprotonation constant of H2O2 in acid medium. Addition of KCl to the mixture increased the rate of reaction. The catalytic activity of the catalysts lies in the following order: Ag-I > Cu-II > Hg-II > Co-II > Mn-II > Fe-III > Ni-II > ZrO2 which is correlated with the redox potential, mg loading and % surface content of the supported metal ions. A probable mechanism for the oxidation processes has been suggested, which is consistent with the experimental results.

Full Text: T\Tra Met Che29, 571.pdf Abstract: The synergistic extraction behavior of Pd-II, one of the main radioactive fission products in the reprocessing process, from HNO3 solutions with a 4-aroyl derivative of 1-phenyl-3-methyl-pyrazolone-5-one (PMP), a weakly acidic chelating extractant 1-phenyl-3-methyl-4-(2-methoxybenzoyl)-pyrazolone-5-one (HPMMBP), and a trialkylamine of high molecular weight, tri-iso-octylamine (TiOA), has been studied. An obviously antagonistic extraction effect was observed in the extraction system under the given conditions. To understand this phenomenon, a preliminary investigation was performed to explain the mechanism of this reaction. According to the theory of the corresponding solutions (TCS), the association between HPMMBP and TiOA is presented and discussed in the organic phase. An associated species HPMMBP TiOA formed through hydrogen bonding in a CHCl3 medium might be the main reason why an antagonistic extraction effect occurred. The association constant between HPMMBP and TiOA was calculated to be 0.212 0.03.

Scientific articles are indicators of research interest and efforts in every country. The aim of the current study is to describe the characteristics of the transplantation-related research efforts with respect to the domestic published works in Iran between 1993 and 2003. Materials and Methods. In a descriptive design, we searched IranMedex (Iranian database for indexing medical articles; available at: http//www.iranmedex.com) for all the biomedical articles published between 1993 and 2003 in 91 Iranian journals. The search was conducted using ‘transplantation’ and ‘transplant’ as key words. A printed copy of the references was reviewed individually so as to identify the transplanted organ, study design, number of authors, and type of article. Results. Among 11371 articles, 545 (4.8%) were related to transplantation. An increasing trend was observed in the number of publications from 1993 to 2003. Most articles were published in Farsi (90%). The most frequently published articles were original articles (84.4%). The main subjects of were kidney (61.7%), followed by liver (12%) and bone marrow transplantation (10.8%). Cornea was the topic of research in only 3% of the papers. Of all manuscripts, 9.5% consisted of clinical trials. The mean number of authors was 3.6 +/- 2.2 (1 to 14). Conclusions. Iranian researchers seem to be interested in the topic of transplantation; however, some fields of transplantation are neglected. This pooling of valuable information can be used by other countries, especially by researchers from the Middle East Society for Organ Transplantation region. Such databases could form an invaluable network for an exchange of experience in the region to solve common problems.

Transplantation Proceedings, 43 (10), 3773-3779. Full Text: 2011\Tra Pro43, 3773.pdf Abstract: Objective. The purpose of this meta-analysis was to compare outcomes after right-lobe living-donor liver transplantation (LDLT) with or without the middle hepatic vein (MHV). Methods. Studies were identified through a computerized search of Pubmed, Embase, Ovid, the Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Central Register of Controlled Trials, the Cochrane Library database, and the Web of Science. Two reviewers independently assessed the quality of each study and abstracted outcome data. We extracted data for liver functional recovery in donors, donor hospital stay, donor complications and liver functional recovery in recipients. We synthesized published data using random-effects and fixed-effect models, expressing results as weighted mean differences (WMD) or relative risk (RR). Results. The 11 included eligible studies came from medical centers worldwide. Significant differences between “with MHV” versus “without MHV” groups were not observed for liver functional recovery (P = .08; WMD = -2.88), donor hospital stay (P = .00; WMD = 0.00), or donor complications (P = .90; RR = 1.02). However, our meta-analysis showed a significant benefit for recipients liver functional recovery favoring the MHV group (P = .02; WMD = -33.06). Conclusions. Our meta-analysis discovered that right lobes with MHV not only experienced better liver functional recovery in recipients, but also caused no greater harm or risk to donors.

Bas, K., Dayangac, M., Yaprak, O., Yuzer, Y. and Tokat, Y. (2011), International collaboration of Turkey in liver transplantation research: A bibliometric analysis. Transplantation Proceedings, 43 (10), 3796-3801. Full Text: 2011\Tra Pro43, 3796.pdf Abstract: Objectives. Scientific publications are valuable markers of scientific activity for countries. We performed a bibliometric study to evaluate the number of publications written by Turkish authors. The aim of this study is to evaluate Turkey’s contribution in terms of number of publications included in Science Citation Index Expanded (SCI-E) in the scientific field of liver transplantation compared with other countries. To our knowledge, this is the first bibliometric study in liver transplantation research of Turkey. Materials and methods. ISI Web of Knowledge-Science was used for the analysis. All scientific works published included in SCI-E in English from 1980 to August 10, 2011, were analyzed. A retrospective search was performed using key words “liver transplantation,” “hepatic transplantation,” “liver transplant,” and “hepatic transplant.” We further analyzed these results by the “analyze” function of the software in terms of number of papers for each country, type of documentation, number of publications per year, journal, institute, and author. The number of citations to published works was calculated by using the citation function of the same software. We also used the same function of the software to analyze publications from Turkey in the last three decades between 1980 and 1989, 1990 and 1999, and 2000 and 2009 for statistical evaluation. Collected data from the comparison periods were statistically analyzed using the chi-square test. Results. In all, 48,418 publications related to liver transplantation were included in SCI-E in English between 1980 and August 2011. Overall, 675 of those publications were from Turkey (2.05%). There was no publication from Turkey between 1980 and 1989; 37 between 1990 and 1999; and 511 between 2000 and 2009. The rank of Turkey among other countries according to the number of publications was 25th between 1990 and 1999 and improved to 14th between 2000 and 2009. The number of scientific publications in the field of liver transplantation from Turkey among other countries increased during the last three decades. Conclusions. Turkey showed a significant positive trend in publications in the scientific field of liver transplantation in the last 30 years, and the rank of Turkey among other countries improved in recent decades. Currently, Turkey is one of the top 17 countries in terms of number of scientific publications listed in SCI-E. This can be considered as another indicator for Turkey’s progress in the field of liver transplantation.
